DO superheroes help with real-life problems in comic books?

[TJanssen411]

Id have batman and iron man donating millions to world hunger and disease research like cancer and leprosy.

-- it is frequently stated that they do these things... "Billionaire, Playboy Philanthropist" isn't just a good sound bite... #3 means he gives to worthy Causes... and in DKR it was stated that before Wayne Enterprises lost money on the Fuel cell/plot device/Bomb that X% of the profits went to Orphans and other charities

Superman could stop wars in africa and middle east. ...
-- Stopping war in the Middle East would be a 28 hour a Day Job... Like Dennis Miller once said the only solution over there is to remember... Sand and Heat Make Glass... when its done it should look like Superman's dad's Place on Krypton and there are too many civilians and World Laws to prevent Superman from taking that action

Thor could stop hurricanes and earth quakes
-- Thor lives in Asgard, and drops by to help the neighbors here on MidGard there is only so much he can do on short notice that such incidents occur
